App1ication filed October 1, i925. sri r 59,8411? p My presentinventionrelates tobrick machines, and more particularly to an im provedcontinuous burning .hood for'usein the continuou's'burning ofa kilnof-brick in a Wide kiln shed. v V I In the burning of kiln's at the'present'day,

particularly the burning of kilns in- Wide kiln sheds, the acceptedmethod is to provide a structure runningparallel with one side of thewalls of the kiln sheds'and on which structure is "arranged one" end ofa plurality of parallelly arranged smoke hoods, the other end of suchsmoke hoods 'being secured to the sidewalls of the kiln shed and attheproper height. Thismethod is'not onlyexpensive because of theamount f ofstructure necessarlly erected, but is also ter'portion oftheikiln to befired is inprocess. of burning long after the bricks comobjectionable..in that it prevents the free, use of the kiln shed after a. portion ofthe kiln hasbe'en burned, 'and a'lso after, the entire kiln has'beenburned andthe bricks corn 1 posing the same carted away. As is wellknown, iii-the continuous burning of kilns the sections ofthe kiln arefired at regular spaced'intervals of time, and the burning of the 'kilnmay be started before the end of the kiln is built up and. conversely,the lat-- posing the. first fired portion of the kiln have been removed.Because'of the perman- .ent structure. necessary to be built in' 'thekiln, it is extremely hard to manipulatecars or trucks andtheconsequence is that the described an. improved apparatus" whereby lthe operation of' the. burning of a continuous kiln maybe performed withthe aidbf a kiln-forward into association with the unminimumamount ofapparatus,such apparatus also employing the idea of Ysmoke hoods, thesmoke. hoods being" relatively fewer in number than the sections of thekiln and provisionbeingmade for gradually moving and erecting sectionsof supporting members from the burned se'ctionsflof the described in'mycopendingapplication I am enabled to provide for the burning .of a

continuous kiln and also forlthe eifioient handling of the brick duringthe erectionof the sections the removing of the burned brick r r m; 1am.the'inajor' portion ofthe' kiln free for theeflicienthanabove referredto, and, in my present invention,;'I provide a gantry:crane structurecarrying, asla permanent fixtureand' on the top thereof, 'a plurality ofsmoke hoods," the number of smokehoodsfhowever, being: con-' slderablyless'than the number o fsectio'ns of kiln that may be built into a kilnshed, and also on such gantry crane structure I provide an improved'm'eans for supportingthe kiln props on the gantrysiden In carrying aplurality of prop supporting m-eanson the gantry slde of the crane'andassoc ate'thera wlth driving means which is, in turn, associout thisportion of my invention I provide .ated with thedriving means for thegantry crane and which will enable the kiln props} to move rearwardrelatively'lto," andfat the same speed a's,'the forward movement-of theciation with the, smoke'hoods a plurality of" maybe coming from the kilnor 'CQflet in accidently stopped d uring the eriodcf-itime.

Further, Iprovide in'asso- SO 7 ing the preferred embodiment of my invento thekiln during the movement of the structure.

A fiurthe r object of my invention is an improved damper means forcontinuous smoke hoods and means for operating the same. I A stillfurther object of my invention 1s an improved means for closing thespace between the top of the kiln and the lower surface'or edge. of 'aplurality of smoke hoods positioned over the kiln.

Reiterring to the drawings, 10' designates a kiln shed, the side wall 11thereof being shown in elevation, and on thetop of such .side wall isshown a portion 12 of the usual roof structure.

The kiln shed may be of any convenient width, and for ease in hand-lingthe brick. it is customary to build the kilns of considerably less widththan the Width of the kiln shed. Such a kiln is shown at'1'3 inendelevation- The building of the kiln 13 of, less width than the width ofthe kiln shed 1 0- necessitates the building of either a temporary or apermanent structure at the side of the kiln 13 remote from the side wall11. tomary tobuild such a structure in perma- .nent form. The permanentform vouistru'cturea, ho-Wever, makes it dlflicult tohandleexpeditiously or economically the brick in the kiln, both during thebuilding of the kiln and, the subsequent tearing down of same forburning. In my present invention I have devised a structure consistingessentially of a rail. 14,. either permanently or temporarily set in thefloor oi the kiln shed and paral lel to, but spaced apart from, the sidewall 1.1 at any convenient distance. On such rail 14 run a pluralityo-fflanged rollers 15 rotatably mounted in suitable bearings in thelower end of a structural iron framework 16 WhlCll forms the gantry endof a crane.

Heretotore it has been cus the lower end of which are rotatably mountedflanged wheels 1.9 rolling one track 20 secured to the inner faces ofthe side wall 11.

Mounted on the horizontal frame 17 and extending from the gantry framemembers 16 are parallelly iarranged smoke hoods 21. These smoke hoodsextend from the'gantry crane members 16 to a point adjacent to the sidewall 11. Mounted on or in the wall 11 and extending transverselytherethrough are a plurality of heat conduits 22, these conduitsentering a conduit 23. The conduit 23 leads to any position where itisdesired to use the excess heat arising from the burning of the kilnand ordinarily to a drying ap paratus. The end of each of the smokehoods 21 adjacent to the gantry crane members 16 are closed and theopposite ends are also provided with closures 2 1 which cooperate withthe inner end of each of the conduits 22.

The inner end of each of the conduits 23.v

smoke hoods throughout their length. In

the tracks 27 are .sl-idably mounted a plurality offda-mper plates 28,these plates 28 be ing connected in series to a cord or similar 7 member29 which extends at either end beyond the limits of the smoke hood, suchends passing over pulleys 3O rotatably mounted in suitable bearings onthe gantrycrane members 16 and the inner ends of'the smoke hoods .21respectively' The cord or similar member '29 makes it possible tooperate the dampers 28 from the ground. The

dampers 28 in association with. the openings I 26 are for use in wastingany water smoke that may be coming from the kiln or to let in cold: air11011161111361" down excessively hot air which may be coming from thekiln, or

which acts as a vent in case the exhaust other, while'the kiln 13 may besix to fifteen times the lengthof such gantry crane members. Therecomes, then the question of properly supporting the kiln 13 against.lat-

eral expansion, and on the inner side of the crane, or the side of thecrane adjacent to .the side frame or. wall 11 of the kiln-this featureis provided. for'by associating with longitudinally extending :members31 and ,32' securedto the inner face of the wall 11 and arrangedparallel to each other the props 33, 7 these props being preferably iwedge-shaped, as shown Fig.1, as such a wedge will, by its own weight,follow up in the space, between the members 31 and 32 and the side ofthe kiln 13 and keep tight. 7

To provide for proper support on the outer side of the'kiln 13 '1preferably provide v parallelly arranged spaced endless chains;v

pairs ofiparallelly arranged members on each side of the gantry cranemembers 16, such members 35 being substantially horizontal, as shown inFig. 2. These members 35 act as'supporting guides and tracks 01 rollers36 rotatably mounted, .top and bottom, to vertically arranged channelmembers 37 Thechannel members 37 are securedto 38, the spacingof themembers 37 onsuch chains 38 being any desired. The top chain 38, asshown in' Fig. 2, runs over a sprocket 39 secured tothe upper end of avertically arranged shaft 40 that is rotatably mounted in suitablebearings 41 on the right hand fmember 16 and also runs over a sprocket'42 secured to the-upper end of a vertically arranged shaft 43 rotatablymounted in bearings 44 secured to the left hand member 16. The lower'chain38 runs over a sprocket 45 secured adjacent to the lower end ofthe vertical shaft40 and also over a sprocket 46 secured adjacent to theleft endof the vertie cal shaft 43. The sprockets above referred to areequal to each other in pitch and di- .ameterso that each of the chains38 runs at the same" speed and in the same direction.

' Secured to the lower end of the shaft 40 is a bevel gear 47 whichmeshes with, and is driven by a bevel gear 48 of equal pitch anddiameter secured to ashaft 49 that is'rotatably mounted in a bearing50formed integral with the bearing member 41.; Secured to the shaft 49is a sprocket 51 over which runs a chain 52j-This'chain 52 also runsover a sprocket 53 secured to the 'shaft55 of m the right handfiangediwheel 15 shown in Fig. 2. The ratio of gearing and chainconnecting the right hand flanged wheel 15 of v the gantry to theparallelly arranged chains 38 is figured to give the same speed in bothcases so that, as the gantry moves forward any given distance, the chaincarrying the members 37 willmovebackwardthe same distance; that is.although the .gantry moves forward, there is no relative movementof themembers 37 opposite the sid'e of the kiln 'wall 11 or to the verticalmembers 3? respectively.

1'3 with respect to such kiln, This construc- .tion enables me to attachto the vertical members 37, as" they come into position opposite'theouter wall-oft the kiln 13, kiln I props consisting of a base member 56into f which passes a screw '57,;the 'hand wheel 58 being'associatedwith said screw," and be.-

wall of the kiln 13 is a'basep'ad 59. Only sufficient kiln props 33, 3401 59 are fur:

tweenthe endjof the-screw, 57and the outer nished for the length of thegantry plusone V extraiand as the gantry moves forward 'releasingthegprops in the" burned end, "they are carried "ahead and attached tothe side As the plurality of hoods '21,'intravelling over the top of thekiln 13,must have a certains 61 may be raised away from thetop of thekiln '13 during the forward movement of the'ga'ntry and associatedhoods. t ithfrny' improved invention only a relatively short gantry isrequired, such gantry extending only for a portion of the lengthof thekiln and being brought successively into association with the kilnasftheburning of the same proceeds. It will be obvious, there fore, that,fwhenno kiln is built in the shed,

the gantry will occupybut a small portion of the shed and, further, whenin posltion ona partially completed kiln, the kiln may be startedburning in sections while the yondwhich'the gantry has passed will leavebuilding of the remaining, portion of the I kiln proceeds,-and, further,as the apparatus is moved along in the COIISBCHUVG' burning ofthesections of the kiln, thus portions bethe bnrnez ljkilnin position tobe readily reached by trucks or other devices utilized inhauling awaythe burned brick.-

"While I have necessarily shown andjdescribed the preferred embodimentof my invention, somewhat in detail, it is-to'be -un-' derstood that Imay vary the size, shape, l I 15 and arrangement ofparts withinwidelimits without departlng from the spirit of the invention; i
